Best Guitar Amps for Metal

best guitar amps for metal

Are you looking for the best guitar amps for metal? This article will help to demystify the amplifier market, especially for those that are metal guitarists.

High-gain and heavily distorted guitar tones are the most important things to look for in a good metal amp.

Many metal guitarists prefer to use natural amp distortion over stomp box distortion pedals. Because of this, an amplifier needs to be able to accommodate not only loud volumes and high gain situations but also be able to produce more than enough natural distortion for any scenario a metal guitarist can throw at it. 

The amplifiers covered will range from the best budget models, the best combo amp, and best practice amp to the best overall. Some of the amplifiers mentioned include:
